World Cup organizers finally had some good news to deliver after one of Brazil’s most troubled stadiums held an important test event without any major setback.

The test match at the delayed Arena da Baixada in the southern city of Curitiba on Wednesday was a step forward, local official were pleased to say on Thursday.

There were some problems during the friendly between Corinthians and host Atletico Paranaense, with fans facing difficulty getting into the venue, but organizers said that was expected as the stadium infrastructure remains unfinished.

“The pressure paid off after we had all the delays with construction work,” said Ricardo Trade, CEO of the local World Cup organizing committee. “There are some adjustments to make, but everything went well.”

The test match happened even though Arena da Baixada was not completed, with seats still being installed and a lot of work to be finalized outside the stadium.

Arena da Baixada is one of FIFA’s main concerns ahead of the June 12 opener. It is one of the three stadiums yet to be completed, along with Arena Pantanal in Cuiaba and Itaquerao in Sao Paulo, which will feature the high-profile match between Brazil and Croatia.

Itaquerao will have its first official test with a Brazilian league match on Sunday.

The nearly 25,000 fans who attended Wednesday’s match saw a lot of construction work underway, with bulldozers parked outside construction material piled up. There was heavy traffic and delays for those arriving at the stadium.

Inside, fans said there were some bathrooms not working, and only a few concession stands were open. The area for the media also wasn’t completed, and the local organizing committee admitted some improvements in communications must be made for the World Cup, which starts in four weeks.

Corinthians coach Mano Menezes praised how the stadium looked but said “inside there are some things that need to be finished, as it happens in almost all of these new arenas being built in Brazil.”

Curitiba organizers also have to deal with a labor court ruling that said constructors must make some changes to avoid irregularities related to workers’ shifts at the venue, but Atletico Paranaense said the needed adjustments were not likely to cause any further delay in the renovation.

Curitiba was nearly excluded from the World Cup this year because of chronic delays that were caused mostly by financial shortcomings.

“We are in the final stretch, there’s not a lot left to be done,” Atletico Paranaense president Celso Petraglia said.

Atletico will try to hold another test match before the World Cup.

The 40,000-capacity Arena da Baixada will host four World Cup matches next month — Iran-Nigeria, Honduras-Ecuador, Australia-Spain and Algeria-Russia.
